This 4" x 1-1/2" drop-forged steel heavy duty kingpinless swivel caster provides the highest capacity, greatest impact strength, and easiest rollability. The wheels are die-formed from pre-heated billets. Precision raceways and fully heat-treated construction make our 71 Series the ideal solutions for applications exposed to rugged conditions or high amounts of impact and shock. 71 Series are more durable than competitors case or induction-hardened construction, and longer lasting than conventional kingpin designs. These kingpinless casters eliminate kingpin failure, the leading cause of caster failure. Zinc plating provides an attractive, protective finish.
